Configuring the units

Configuring the units for determining cleanliness class of oils and other working fluids

We carry out laboratory analyses of basic physicochemical parameters of the oil. Results, in the form of a statement are conveyed by means of electronic mail (e-mail) or as hard copies by means of surface mail.

Analyses of basic physicochemical parameters:
No.Determination/analysis typePerformed as per standard
1. Density at temperature 20°C (g/dm³) PN-ISO 3675:1997
2. Viscosity at temperature 40°C (mm²/s) PN-81/C-04011
3. Flash point (°C or K) PN-82/C-04008/
4. Water contents — distillation method PN-83/C-04523
5. Acid number (mg KOH/g of liquid) PN-81/C-04066
6. Cleanliness class (microscopic method ISO 4407) PN - ISO 4407
7. Corrosion on copper/steel plate at T = 120°C PN-85/C-04093

We offer also analytical services in scope of other oil parameters in co-operation with scientific institutions accredited to perform analyses listed in the following table.

Analyses of other oil parameters:
No.Determination /analysis typeAs per standard
1. Water content —K. Fischer method, sensitivity up to 5 ppm   PN-81/C-04959
2. Emulsifying power PN-86/C-04093
3. Determination of the demulsification number PN-79/C-04110
4. Resistance to oxidation ASTM D2272 (RBOT)
5. Foaming power PN-85/C-04055
6. Oxidation inhibitor content spektrometria IR
7. Air releasing power at 50°C PN-79/C-04174

When sending a sample, please attach the type of analyses required and attach (or send separately by facsimile or e-mail) the following details concerning the sample (if available):

  • oil type (or name) and manufacturer,
  • oil usage time,
  • machine or device in which the oil is used,
  • capacity of the oil reservoir,
  • sample taking date.

The container (a plastic bottle or a glass jar) should be clean and dry. Do not forger to protect the container with the sample against mechanical damage in transportation.
